Abstract: Abstract of the Disclosure A microwave heating device is comprised of a micro-wave reflective member having positioned adjacent thereto magnetic microwave absorbing material.  The absorbing material, by being magnetic, will heat by coupling of the magnetic component of microwave radiation.  The thickness of the absorbing material is such that at the Curie temperature the material will reflect at least about 65% of the incident microwave radiation.  The absorbing material has a volume resistivity value R, at room temperature, in ohm cm of greater than about the value where Log   + 2 where Tc is the Curie temperature (°C) of the material.  By the proper com-bination of thickness, high resistivity and Curie temperature, the device is temperature self-limiting in a microwave field and can be used to heat objects in contact with the device to predetermined temperatures in spite of wide fluctuations in microwave power or power uniformity.

Abstract: ABSTRACT OF THE DISCLOSURE            The present invention relates to a screw having a star-shaped socket hole in a top surface of the screw head.          The star-shaped socket hole has the form of the figure formed by concentric superposition,   45° out of phase, of two equilateral octagons intermediate in configuration between a regular octagon and a square.  The screw can sustain high tightening torque values, and reduces the risk of chipping and deformation in the screw head whilst facilitating the fitting of a screwdriver in the socket hole of the screw.

Abstract: VENTED WATER DISTILLER     ABSTRACT OF THE DISCLOSURE         A batch operation water distiller is provided with a venting valve between the boiling chamber and the condenser.          Operation of the venting valve during the heating phase prior to boiling allows entrained gases such as chlorine to be vented to the atmosphere rather than into the condenser and hence into the purified water.  The valve may also be used as a humidification device for the area in which the distiller is operated.  A screen-like shield is provided about the condenser inlet so as to prevent bubbles of unpurified water from entering the conden-ser passage.  Also, a flexible fill tube is provided which allows the distilling chamber to be filled prior to use and then drained after use so as to remove mineral laden water from the chamber.

Abstract: ABSTRACT OF THE DISCLOSURE         This invention relates to mechanical double acting mechanism for actuating valve pins in a valve gated injection molding system.  A number of valve gate units are aligned with a pneumatically driven toothed rack member.  The rack member engages a hollow rotatable pinion member which is secured in each unit against transverse movement.  The driven end of the valve pin is fixed in a bushing which extends through the pinion member and threadably engages it.  The valve pin is actuated between the open and closed positions by longitudinally driving the rack member which rotates the pinion member and the bushing.          In addition to providing a reliable and relatively inexpensive actuating mechanism, provision is made for relative axial adjustment of the valve pins prior to the commencement of operation which provides accurate valve seating without unduly high manufacturing tolerances.

Abstract: SOLENOID-OPERATED FUEL FLOW CONTROL FOR          FUEL INJECTION SYSTEM                 Abstract of the Disclosure A fuel flow control lever is pivotably mounted for movement between fuel-off and fuel-on positions wherein it respectively engages first and second stops.  A solenoid has its plunger linked to the control lever and when the solenoid is de-energized, a spring acting on the plunger holds the latter in an extended position wherein it holds the lever in its fuel-off position.  A pair of coils surround the plunger and are selectively simultane-ously energizable to retract the plunger to effect movement of the lever to its fuel-on position.  The linkage between the plunger and lever is yieldable and the lever reaches its fuel-on position prior to the plunger becoming fully retracted.  Upon the plunger becoming fully retracted, a normally closed switch is opened to de-energize one of the coils.

Abstract: TWO SITE CROSS-REACTION IMMUNOMETRIC   SANDWICH ASSAY METHOD     ABSTRACT The present invention relates generally to immunological assay techniques for determining the presence of an analyte in serum and more particularly to a two site cross-reaction immunoassay sandwich testing method which has particular application In the qualitative and quantitative determination of the level of the creatine phospho-kinase MB isoenzyme (CK-MB) in serum.  Conventional immunometric techniques depend upon the immunochemical reaction between a tagged antibody which is raised to specifically react with the particular analyte of interest.  However, such antibodies may not be available, or if available, then unstable.          The disclosed two site-reaction immunometric sandwich assay method provides for the selection of two different antibodies each of which is specific to a different analyte but each of which will cross-react with the analyte of interest.  The first antibody is reacted with the unknown sample of utilizing a solid-phase to bind the first antibody.  Separation of the solid and liquid por-tions of the first reaction is accomplished and the solid portion thereof is reacted with the second antibody which is tagged.  The solid portion and liquid portion of the second reaction are separ-ated and the solid portion is tested for the tag as an indication of the presence of said analyte.  With particular reference to test-ing for creatine phospho-kinase-MB In human serum, the cross-reacting antibodies utilized are antibody to creatine phospho-kinase-BB and creatine phospho-kinase-MM.

Abstract: MICROWAVE HEATING APPLIANCE AND METHOD                  Abstract A microwave heating appliance having a metallic member supporting a body comprising ferrite bonded to an outer surface of the metallic member with a grooved inner surface of the metal-lic member contacting a food body to be heated by thermal energy generated from microwave energy absorbed by the ferrite body and transferred through the metallic member to the food body.          An additional metallic member forms a container for the food body, and adjacent peripheral areas of the two metallic members provide substantial microwave sealing between the two metallic members thereby substantially shielding the food body from the microwave energy when the appliance is placed in a microwave oven.  Upper and lower surfaces of the interior of the appliance contain grooves to form corrugated surfaces which contact the food body and which permit juices produced by heating the food body to flow away from regions of contact between the corrugated surfaces and the food body.

According to the invention the pressure of this "soft" air is varied according to the viscosity of the particular color being dispensed so that a constant delivery rate and coating thickness is maintained right up to the end of delivery of that particular color.  A similar "soft" solvent technique is also disclosed.
